A Wisconsin woman looking to move to New York found herself living a nightmare after a man who lured her to Brooklyn through Craigslist with the promise of rent-free digs allegedly subjected her to more than a week of sexual torture.

The victim, 27, e-mailed John Hopkins, 45, about his Web ad, which said he had a room in his East Williamsburg apartment, police sources said.

After telling her she could stay for free if she cooked and cleaned, Hopkins paid for her plane ticket and picked her up at Kennedy Airport on Feb. 4, according to the sources.

As soon as they arrived at his place on Humboldt Street, Hopkins allegedly told the woman that she was to be his slave. He then allegedly blindfolded and gagged her, handcuffed her to a radiator, and began beating and raping her.

For the next eight days, Hopkins allegedly kept the woman chained in his apartment, but then allowed her to leave for a job she had landed at a Manhattan restaurant.

Bizarrely, the woman did not call 911 while she was away from her alleged tormentor. But last Saturday, she contacted her mother, who alerted the NYPD. When cops arrived, they found her shaking on Hopkins’ bed. She was treated at Woodhull Hospital.

Hopkins was hit with charges including rape, assault and unlawful imprisonment.
